Making the Invisible Visible.

Civilian Airspace Monitoring in Real Time. Completely Passive. License-Free Operation. Made in the EU. Ideal for Critical Infrastructure.

The Threat from Above Is Growing

Drones and other airborne objects are increasingly posing a risk to sensitive infrastructure. They often go undetected—until it’s too late.
Our system provides visual clarity in an area that has so far remained blind.

How Airspace Monitoring Works

Drones (emitting / non-emitting)

Light aircrafts / helicopters

Birds / other objects

Interference signals & jamming

Flying objects

Detection, classification, and identification of drones, helicopters, airplanes, and other aerial objects.

Multi-sensor system

The mobile ground-based multi-sensor system can be mounted in a trailer or installed permanently with an antenna mast. Three sensors reliably monitor areas such as industrial facilities or airports.

Unified management interface

Airspace situation display shows drone positions for incident events. Browser-based and accessible via mobile devices.

Three mobile sensor units are strategically positioned around the area to be monitored. Without emitting any signals themselves, they detect everything moving in the airspace – whether it’s a radio-controlled drone, a glider, or a flock of birds. Data from radio, radar, and telemetry sources is merged in real time, providing a comprehensive and seamless overview – reliable, discreet, and operable without a license.

The advantages of such combined technology go beyond mere threat prevention. Precise detection enables the collection of evidence and detailed analysis after an incident. This is of significant importance for clarifying causes (such as in the case of an unexplained crash) or for insurance matters.

Furthermore, the system provides substantial organizational value for the event organizer: Authorized drones, for example from media partners or emergency services, can be automatically recognized by the system and assigned to the responsible parties. This simplifies the coordination of approved air traffic and allows for quicker differentiation between authorized flight movements and potential threats.

Integrated solution for GNSS monitoring and drone detection

The security company hensec is currently the only provider offering a comprehensive and integrated solution combining GNSS quality monitoring (spoofing and jamming detection) with advanced drone detection, including the recognition of non-cooperative drones. Conventional GPS jamming detection systems merely identify that a signal is unreliable but cannot distinguish whether the issue is interference, jamming, or spoofing. In other words, they detect that something is wrong, but not what exactly. The hensec solution, however, provides an extensive analysis of GNSS signal quality in multiple aspects, allowing even sophisticated spoofing attacks to be detected and immediately countered, for example by blocking manipulated radio signals.

The GNSS components already comply with the latest EU guidelines.

Our sensor technology in combination

Our system combines leading technologies from various fields of passive airspace surveillance — developed and operated by experienced European specialists.

incorporates highly precise radio detection and system integration — including hardware from Aaronia and GPSPatron.

provides a passive radar method that also makes non-radio-emitting objects visible — completely discreet and license-free.

complements the system with powerful radio telemetry based on Avionix hardware.

Together, this creates a unique, civilian all-in-one solution for critical infrastructures – modular, scalable, and fully "Made in the EU."

Radio detection (hensec / aaronia)

Detects radio-controlled drones and transmitters precisely in real time.

Passive radar (parasol)

Detects non-transmitting objects based on reflections of existing signals.

Radiotelemetry (airsenso / avionix)

Uses flight telemetry data for precise localization.

GNSS Jamming Detection (GPSPatron)

Detects GPS interference and spoofing attempts.

Everything on one screen

All sources merge into a clear situational picture — centralized on a single screen.
